Paramount PAR37203 Hex Key 1/16 Inch Short Arm

Product Description

The PARAMOUNT PAR37203 is a short-arm hex key sized at 1/16 inch, designed for driving hex socket fasteners in confined spaces where a long arm would not fit. The overall length is 1-51/64 inches (approximately 45 mm), making it compact and easy to maneuver in tight clearances. The hex end engages directly with socket head cap screws, set screws, and similar fasteners. This tool is used by HVAC technicians, plumbers, electricians, and mechanical tradespeople whenever small hex fasteners need to be seated or loosened during equipment service or installation.

The short-arm configuration is best suited for applications requiring low torque and precise positioning in restricted areas, such as adjusting set screws on motor shafts, tightening fasteners inside control panels, or servicing equipment with closely spaced components. Its compact profile makes it practical for tool pouches and service kits where space is limited.

Installation Notes

This tool is used by any trade professional servicing mechanical assemblies with hex socket fasteners. Power down equipment and de-energize all circuits before accessing fasteners inside electrical enclosures or control panels. Apply steady, controlled force to avoid rounding the hex socket, particularly on small fasteners at this size. No special certifications or codes govern hand tool use, but always follow site safety and equipment manufacturer service procedures.
